Too]? vii/20m it may concern:

Be it known that l, .lilvnnnrr W. i-XBNEY a citizen of the United States, residing at Newton, in the county of Middlese and State of Mi-issachusetts have invented certain In1 tion, like reference characters on the drawings indicating likefiparts in the severe figures. I j

'lhis inventionrelates tolasting machines and particularly to toe lasting mechanism and has for its object to liner-ease the capacity and improve and simplify the construction of mechanisms for lasting the toes of shoes on right and left crooked lasts.

For many styles of shoes'right and{left wipers must be provided to fit the different contours of the toe portion of theJlasts for the right and left feet. been proposed to equipthe toe lasting mechanism with two pairsof toe embracing wipers and mount the head for adjustment, as, for sample, for rotation to bring either pair of wipers into positionto operate on a shoe.

it has also been proposed to provide an end 7 mechanism with two pairsof end em- .g wipers superposed onepair above ie other with means for bringing either air into operative position for lasting a no toe. one pair being shaped to fit a right toe and the other shaped to fit a left hoe toe. Neither of these constructions, owemer. has come into general use partly at t oeciuise of the bulkiness ofcomplicaof such mechanism. and the practice is still followed almost entirely of taking out one pair of wipers and substituting a pair the other feet when changing from right or ieft'shoes... This changing of wipers makes it i'lecessary to last first a series hoes for one foot and then the mates to th qe shoes, it being impracticable, except on sample work, to take time to change wipers and last mates alternately, although oliiviously the best results are obtained hy lastin mates successivelv iand inatchin 2': b

same horizontal plane and movabletrans-- versely of the shoe to bring either pair into operative position with operating mechanism by which either pair can he used.

Another feature of the invention consists in operating mechanism for either of the two pairs of wipers whichis so arranged that movement of the operating lever beyondvits normal movement for opening the wipers will unlock the moving slide which carries the wipers and enable the pair which is in use to he moved out of operative position and the pair which is out of operative position into position for use. a

These and other features of theinvention w1ll appear more fully frointhe following description when read in connection with the accompanying drawings and will he pointed out in the claims. i it Figure l is a perspective view showing the head of a bed lasting machine equipped with this invention;

Fig. 2 is a section on the line22 of Fig. 3; Fig. 3 is a perspective view, partly in section, showing in detail the manner of con set ing the wipers to their operating mechanism. i J r in the drawings the toe portion of a right shoe is represented as supported on a toe rest 2 and held down upon it by a hold-down l, a pa' or set of wiper plates ,6, 8 being shown as holding the upper in lasted position upon the feather of the innersole of the shoe toe. The wipers 6 8 may be of'usual construction. end are shown as detachably held in carriers 1C, 12 which are guided for forward and cl sing movement by roll studs ll, 16 mounted between upper and lower plates 18, 20 spaced apart by blocks 22 to which they are secure l and formingwith the blocks a wiper tran ring slide. The transferring is is mounted for sliding movement tran sely of he shoe in a nember which e tends forwardly above the plate 18 and beneath the plate 20. The plate 18 has a groove 26 which is engaged by a rib 28 on the member to guide the slide in its transverse movement. The 'meinher 24 has a cylindrical portion 30 which is arranged to be tilted transversely of the shoe by a screw S'l provided for as usual by a screw 32.

marrow, OFPll-EERSON, NEW amt,

An operating rod 36 is connected to a lever 38 by which it is moved longitudinally through; the cylindrical portion 30 of the member 24 and at its forward end is arranged tor operative connection with the cross head.

Obviously, longitudinal movement of the rod 36 by the lever 38 will move the cross hcad 12 in the direction of the rib lt and cause the wiper carriers 10, 12 to advance and close the wipers 6, 8.- V

ltwill be observed that the wiper transfer-ring slide has su'llicient lateral extent to accommodate a second pair of wiper carriers 50, 52 with their accompanying wipers 56, which may be the wipers tor a left shoe which is a mate tor the right shoe for lasting which the wipers 6, 8 are adapted.

The mechanism tor operating the wipers 56, 58 is substantially identical with that for operating the wipers 6, 8, except that a fork 2e erated, there is provided in each of the cm the shoe to permit operative movement or the cross head relatively to the member (SOcorresponding to the fork d0 is arranged with its opening directed oppositely to that of the fork 40 so that when the wiper transherring slide is moved in the member transversely ot the machine the fork 60 will engage the notches in the rod 36 and the wipers 56, 58 may then beoperated by the rod 36inthe same manner as the wipers 6, 8i when the transferring slide s ad usted as vshown in Fig. l.

To look the transferring I movement while either pair of w s heads 42 a pin 62 which extends thrinigh a slot in the plate 20 of the slide and engages a groove 64; in the portion of the member 94. which extendstorwardly under the plate 230,

The groove extends longitudinally of 4 411., and from the groove 64 lateral 'grooves 68 extend transversely of the direction of operative wiper movements, the outer end portions of the groovcsGS being bell mou oj'to enable the pin 62 of the cross head 4i is in inoperative position to find the slot when it is moved to operative position even though the wipers have, by accident or intention, been partly or wholly closedwhile in inoperative position. It is desirable to hold the wiper transferring,- slide lockedagainst transverse movement until intentionally released by the operator. To unlock of the rod 36 will be in alinernent 1 forks t0 and 60 as the slide 18 IllOYtt t 1 notches inthe rod, the torks being for adjusting theinachine for last the slide, in the construction described, it is only necessary to move the lever 38 to the rearward limit of its movement, thereby bringing the pin 62 of thecross head which 18 1n operative posit on opposite thopen'ng otthe transverse groove 68 in the meme or 24, and to prevent unintentional movement posite the opening of the transverse ,e'rooie 68 n the member 2 lhe slide can then be moved to bring pin 62 on the other cross head 12 into alinementwiththe groove fi l which it will enter and where it will normally remain when the lever is On the opposite ends of the slide, Stops KM are provided which so limit movement of l: r slide in either direction that when at e ther limit one or the ot V in alinement with the groove 6%.

The movementot the lever 38 again?" spring pin 70 is so limited that t x, cannot be moved rearwardly beyond th sition where the notches in the end i either of them into engagement with always set automatically in their rearwa. position by the action of the on the pins 62.

In the construction described it be seen that very convenient means is nrovided 5; either right or left shoes, the adjustment l k made without the necessity ct n snipulatin any additional or awkwardly placed levers and without consuming any material amount or" the operators time a a so that, since both sets of wipers are in the same plane, the vertical position of the toe lasting: head, which is, as usual, controlled by a toot treadle, is the same for one set of wipers as for the other. It is therefore practicable withthis machine to last shoes in pairs the right and left alternately.
